The Kubernetes kube-controller-manager in versions v1.0-1.14, versions prior to v1.15.12, v1.16.9, v1.17.5, and version v1.18.0 are vulnerable to a Server Side Request Forgery (SSRF) that allows certain authorized users to leak up to 500 bytes of arbitrary information from unprotected endpoints within the master's host network (such as link-local or loopback services).

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5727 advisory.

  - A vulnerability was found in all versions of containernetworking/plugins before version 0.8.6, that allows     malicious containers in Kubernetes clusters to perform man-in-the-middle (MitM) attacks. A malicious     container can exploit this flaw by sending rogue IPv6 router advertisements to the host or other     containers, to redirect traffic to the malicious container. (CVE-2020-10749)

  - The Kubernetes kube-controller-manager in versions v1.0-1.14, versions prior to v1.15.12, v1.16.9,     v1.17.5, and version v1.18.0 are vulnerable to a Server Side Request Forgery (SSRF) that allows certain     authorized users to leak up to 500 bytes of arbitrary information from unprotected endpoints within the     master's host network (such as link-local or loopback services). (CVE-2020-8555)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

  - The avatar feature in Grafana 3.0.1 through 7.0.1 has an SSRF Incorrect Access Control issue. This     vulnerability allows any unauthenticated user/client to make Grafana send HTTP requests to any URL and     return its result to the user/client. This can be used to gain information about the network that Grafana     is running on. Furthermore, passing invalid URL objects could be used for DOS'ing Grafana via SegFault.
